Ferrous fumarate and ferrous succinate are both drugs for the treatment of iron-deficiency anemia, and it is not possible to generalize which one is better, as the specific therapeutic effect varies from person to person.
Ferrous fumarate and ferrous succinate are common drugs used in the prevention and treatment of iron deficiency anemia, and should be contraindicated in people who are allergic to the product, people with high iron load, people with non-iron deficiency anemia, people with severe damage to liver and kidney function (especially untreated urinary tract infections), and people who suffer from hemochromatosis or ferrous hemoflagellinosis.
Adverse reactions associated with gastrointestinal symptoms such as nausea, vomiting, constipation, and epigastric pain may occur after administration. During the treatment period, blood tests and changes in serum iron levels should be periodically reviewed.
Both of the above drugs have the effect of iron supplementation, the specific effect of the drug varies from person to person, so it can not be generalized which one of these two drugs is better. The specific use of drugs should be carried out under the guidance of specialists, not unauthorized use of drugs.
